IntroductionWelcome to ChattyInfty! ChattyInfty is a mathematical document editor to provide speech-ou

9、tput access while reading, writing or editing scientific documents. This software was developed by the Science Accessibility Net Project. Our organization also offers many services to help visually disabled people with accessing scientific information. Please visit the web site of Non-Profit Organiz

10、ation, Science Accessibility Net (or sAccess Net, shortly), 1.1 Features* Math expressions or scientific documents ranging from secondary education to higher education levels can be written or edited by using the keyboard with speech output. * Files made by ChattyInfty can be saved in various access

11、ible formats: LaTeX, MathML, PDF, or HTML. IML (Infty Markup Language) format is essentially XML and is completely compatible with other Infty software: the math OCRsoftware, InftyReader and the Math-document editor for sighted people, InftyEditor.Information displayed on the main window of ChattyIn

12、fty is completely equivalent to that of InftyEditor. All of math expressions are displayed in the ordinary print style. ChattyInfty reads aloud not only texts but also those math expressions. Visually disabled students can access, write or edit scientific documents including math expressions, with s

13、peech output. They, therefore, can share the same educational materials with their classmates. Their teachers can easily prepare those materials by making effective use of InftyReader and InftyEditor. Furthermore, the teachers can directly read documents that visually disabled students draw up even

14、if they are not familiar with Braille.1.2 System RequirementsThe operating system should be either Windows 2000, XP or later. The Microsoft Internet Explorer 6 or later must be installed. Microsoft speech API version 4 must be installed.2. Installation and ActivationPerform setting.exe in the Chatty

15、Infty folder and follow the instructions. After installation, you will be asked to complete the on-line activation. You can find information about them on our web site: 3. Getting Started3.1 How to InputChattyInfty is started by Text (input) mode. In this mode, you can write or edit literary texts w

16、ith the keyboard. To input math expressions, press Ctrl + Space key to switch to the Math (input) mode. By using this key stroke, you can switch between Text and Math input mode. Remark:You can change the shortcut to switch them, using setting menu.You can set up different voices for each of text an

17、d math parts with Speech menu.3.2 Using Math Input ModeTo input characters or symbols which are not on the keyboard, ChattyInfty provides two methods as follows:3.2.1 Keyboard-based input methodEnter followed by specific name (the TeX command), then convert it with Space key or Enter key. For instan

18、ce, if you want to input Greek letter alpha, enter alpha from keyboard and then press Space (or Enter) key. When you start inputting the command, the choices that have the same initial letters are displayed; so, you can choose an appropriate one from them.3.2.2 Menu-operation-based input methodSelec

19、t from the Context menu that pops up by the Application key (or right click). How to do it will be explained later.Up to five Characters recently selected are displayed in the Context menu. It may be convenient when you use same characters repeatedly. See Input reference (List of characters and symb

20、ols) in the Help menu for the character/symbol commands and their classification. Apart from Math-mode symbols, Latin character sets in Text mode are also available from the symbol lists that pops up by pressing the Application key (or right click).3.3 Creating Math Formulas3.3.1 Superscript and Sub

21、scriptTo write an x squared, do the following:1. Type the base letter, x.2. Press the Up Arrow key or Input (hat). The cursor will move to the superscript position, and ChattyInfty will say power. 3. Type the 2 and press the Enter key. The cursor will return to the base line.To write a x sub n, do t

22、he following: 1. Type the base letter, x.2. Press the Down Arrow key or _ (Under-bar). The cursor will move to the subscript position, and ChattyInfty will say sub.3. Type the n and press the Enter key. The cursor will return to the base line.Remark:Using the setting menu, you can change the setting

23、 so that, instead of the Up/Down arrow keys, the Ctrl + Up/Down arrow keys moves the cursor to the super/subscript position. At that time, the Up/Down arrow key simply moves the cursor to the previous/next line.3.3.2 Special CharactersAs was mentioned previously, mathematical characters that are not

24、 on the keyboard can be input from the Context menu that pops up by pressing the Application key on the keyboard, pressing Shift F10 or right clicking the mouse. In the Character/Symbol set, there is a list of many special characters. To write a Greek letter, alpha, do the following:1. Press the App

25、lication key to open the Context menu. ChattyInfty says Context menu.2. Press the Down Arrow key several times to find an item, Character, Symbol.3. Press the Right Arrow key to move to the submenu; then, ChattyInfty says Greek.4. Press the Right Arrow key to move to the entry list of the Greek lett

26、ers.5. Select alpha and press Enter key.You can input a variety of special characters from the Context menu.To write a symbol of is greater than or equal to, do the following:1. Press the Application key to open the Context menu. ChattyInfty says Context menu.2. Press the Down Arrow key several time

27、s to find the item, Character, Symbol.3. Press the Right Arrow key to move to the submenu.4. Press the Down Arrow key to find an item, Relative Symbol.5. Press the Right Arrow key to move to the entry list of the relative Symbols.6. Select the symbol of is greater than or equal to and press Enter ke

28、y.3.3.3 Math SyntaxBesides the superscript and the subscript, there are many special notations in mathematics. We call them Mathematical syntaxes. They can be also input from the Context menu. To input characters/symbols in a place other than a base line such as fractions made of a denominator and a

29、 numerator, radicals in which characters and symbols are written in certain layout or other math syntax with super/subscript around symbols (a summation, for instance), the following methods are provided.A. Keyboard-based Input MethodFirst, enter followed by a certain name (TeX command) and then, pr

30、ess the space (or Enter) key. The cursor moves to inside of the syntax so that you can enter characters and formula. If you need to enter super/subscript area in the syntax (the index in radicals, for instance), press the right/Left Arrow keys after entering the base characters; then, the cursor mov

31、es to the positions that need to be input.B. Menu-Operation-based Input MethodSelect the syntax from the Context menu that pops up by the Application key (or the right click). Pressing Arrow keys to let the cursor move to inside of the syntax; then, you can enter characters and symbols in it.You can refer to Input quick reference(Mathematical Syntax List) in the Help menu to check each command and input method.To write the fraction, one over two do the following:1. Press the Application key to open the Context menu. ChattyInfty says Context menu.2. Press th
